Hi Otto,

I'll try to list the reference docs that probably address your points:

- If you plan to have devices/users in Kazoo, you can use the quickcall functionality[0] to connect them to a phone number. Includes setting custom caller ID. Some folks build queues using conferences and you can dial out[1] from them as well

- With the channels[2] API you can query active channels per account/user/device.

- With the CDRs[3] API you can fetch CDRs over a range of time

- You can setup call recordings automatically for devices/users/accounts (see [4] for example). You can also enable them on-demand in the callflow (JSON tree that determines how to process a call).

- Depends on whether you bridge two callers together or put them in a conference how you implement these features but definitely do-able.

From what you've described, your use case fits in our sweet spot of providing the infrastructure for you to build on. You get the scaling of your app for free by using Kazoo, in that Kazoo presents one logical soft-switch while taking care of the bookkeeping of which media server calls and conferences actually exist on. You can setup Kazoo yourself to play with it (currently recommendation is to use CentOS[5] but Debian is coming), knowing that we have professional services and SaaS/PaaS/Iaas offerings to get you going faster as well.

Hope that helps!
